THDZ-1745 Passive Piezoelectric Buzzer [4KHz] is a small 17mm round passive buzzer that sounds around the audible 4kHz range. It can be driven directly from a 3v to 5V Arduino or microcontroller to generate simple melody. The buzzer leads are terminated with male pin. By applying a DC voltage, It can't generate any sound.

Rated Voltage (Square Wave): 5~12Vp-p
Operating voltage: 1~30Vp-p
Rated Current (MAX): 24mA
Sound Pressure Level (SPL): 75~85 dB (at 10Cm)
Resonant Frequency: 4KHz
Operating Temperature: -20°C ~ +70°C
Diameter: 17mm
Thickness: 4.5mm

This passive buzzer requires a square wave (PWM) signal to make a sound or to play melodies. The frequency of this PWM signal will determine its sound tone.
